v Chicago, Ill., a corporatien of'lllinois M Application June 17, 1932,. Serial No.617,s 1'z I 17 (o 51-1c4) This-invention relates to tumbling barrels or thelike; T Among other objects, the invention'aims to provide an improved barrel which 'occupies a mini- 6 mum {of space and which is at' the same time sturdy and eflicient. I

Another object is to provide means for mounting the barrel and a motor therefor'upon, a

frame-within which the barrel rotates and which 1 is swingable toplace the barrel in selective charging,'running or unloading positions, .thus effecting great economy of time and effort;

- Still another object is to provide a removable closure for the barrel, one of the stub shafts upon which the barrel rotates beingcarried by said closure, and simple and eflicientmeans for removing and replacing the closure; 1

Other objects and advantages willbe apparent from the following description of the illustrative embodiment of the'invention shown in 'the'accompanying drawings, in which Figure 1 is aside'elevation ofa structure embodying the invention, showing one position of the parts in'fulllines and anotherposition in, dotted lines; y l i 1 1 of the structure shown: p

Figure'3 is an end view of the structure shown in Figure 2, taken from the righthand side of Figure 4 1S9; plan section'of theframe and barrel taken on the'line '44 of Figure 1 ,'o;ther

parts being omitted: and v Figure 5 is afragmentarys'ide elevation of the structure'of Figure 1 showing the latching mefans f for the frame; 7 Referring in detail tothefigures of the draw ings, I have shown in general a base 1 which jcomprises four spaced apart pedestals 2-and spacedapart horizontal girders '3 together with trans-- verse reinforcingmembertia therefor. .Theg'irders 3 'may be supported on the pedestals 2, but 'at their ends opposite the member 3a the girders [3 are unconnected, so that [between each pair'of girder 'and pedestal may be received a frame 4,

The longitudinal side'rnembers 5 ofthe'frarne 4 a are desirably 'efchannel iron formation and are "fprovidedmedially of their ends withtrunnions 6 which ar'e received in" trunnion sockets '7 at side members 5 of the frame 4 are'maintained infixed spaced apart relationship by a collar 10 having lugs 11 suitably secured'within the channels of the members 5 for a purpose presently pointed out; 'So constructed and arranged} the frame4 is swingable in a vertical plane upon the base 1 on' 1' an axis passing transversely through'the longitudinal side members 5 a Received between the side members-5 of the frame 4 is the tumbling barrel 12 which may com- :5 prise a'metal cylinder 13 closed at one end by the 2 integral end wall 14. Fixed to'the end wall 14 of the barrel 12, by suitable screw bolts such as 1 indicated at 15, Ihave shown a gear wheel 16 which, in this instance;-is provided with the in- 20 ternal gear teeth 17. Carried centrally by the 9 gearwhe'el 16 isa stubshaft 18 which may be pressed into the hub of the gear'wheel and which is Ejournaled in the bearing block's constituting one of the frame end members through the in- 7 V *termediationof axially aligned anti-friction be'a'rings 19 and'=20 carriedby; the bearing block 8. The outer end ofithe stub-shaft 18 is advantageously covered by a 'guardpl'ate 2lwhich pro- [tects the bearings from dirtfetc. When the stub.

shaft 18 is inthebearing's "19' and 20-as' is supported within the frame 4: and-collarlo' to be rotated therein and also to be swing'ablewith the framed in a vertical plane; ;By reason of the.

aligned bearings the barrel 12is supported'free' of the collar 10, but should some slight tilting of .fthe barrel occur thefcollar' "10 will unobjecti'on ably supportthe outer, end of the barrel. At its'end opposite-the bearing'block' athep frame! has another transverse f end memberf representedby'the bearing-block 23 which is separable from the frame 4; -but-,is adapted to be receivedfbet'ween the side members 5' and, clampedthereto The barrel12 also hasan end 9 24 which forms-a closure for the barrel 'andij which is-rerhovable, as here shown with the bearing block 23. The bar-rel end- 24 carries centr'ally, as by'apress fit, a stub shaft25 which is journaled in the bearing block 23l-throug'h thefits snugly -over the cylinder l3 and may also bejm provided with a gasket 29 which makes the barrel 'watertig'htl The bearing block 23 may be clamped within the channels of thesi'demembers '5' by clamping means. such as the cam discs 30. ii jfixed: to 'rotate on braclretsBl' carried by the 0 outer faces of the side members5. By means of the levers 32 the cam discs 30, which have cutaway portions 33 and cam surfaces 34. may be rotated to have the cam surfaces 34 engage the bearing block 23 and press it into assembly with the frame 4, or. may be rotated vto have the cutaway portions 33 adjacent the bearing block 23,

so that. this block and with it the barrel end 24 may be removed. It will be understood that when the bearing block 23 is clamped in position as described, the barrel end 24 is also clamped upon the barrel cylinder 13 to form hoth'a'closure therefor and a carrier for one of the stub shafts upon which the barrel rotates, When the'qbearings 19, and 26 are thus aligned-the axis 10f the, barrel is fixed and the barrel rotates freely of the collar 10 and of all other parts @of the frame 4. e

The barrel is desirably rotated by a conventional electric motor- 35 which has a driving pinion .86. meshingwith a'gear v3'7 fixed on a shaft .38 carried eccentrically by the bearingv hlockfi through the intermediation of an antiat. 41a (Figure1) Thus the motor and the :barrel areboth mounted on the frame 4 and are The side frictionbearing 39, the shaft 38 at its end opposite gear v3'7 and upon the opposite side of the .belring block v8 also carrying a pinion 40 which meshes with the. internal gear 17 of the gear wheel 16. ,Themotor 35. is supported by a platform 41 carried by the frame 4 as by being-suit- ;ably bolted to the bearing block 8 as indicated swingablevas a unit with the frame.

members 5 of the frame are desirably continued beyond the bearing block .8 as indicated at 412) frame is swung as described,

For a-charging position ofthe .bearinghlpck .23 and barrel end 24 removed, as shown in dottedlines in Figure 1; Since these parts areiof considerable weight, I have provided a mechanical aid for lifting these parts from the Jrame, here represented by the -jib 42 which is .showhof inverted U-shape, spanning the base 1 ..and pivoted tothe girders 3 at,43. Two hooks 44 may be suspendedfrom the horizontal cross piece qf=:the U shape' .jib 42 and these hooks may engage in eye-bolts;-45,suitably secured to the bearingjblock 23. The jib 4271s desirably moved toward =thebarrel12 against the action of springs 46. .80 that the jib. when released is normally retracted to be'out of the. way of the barrel. Stopsd'l vmayliniit the movement of the'jib away from-the i the sideof the trunnion fiawayfrom the closure =end=of the barrel, thus effecting ,a positionof stable equilibrium for v the frame .I when -in 'the vertical-position shownindotted lines in Figure 6.

When-thehooks 44 are engaged in the eyebolts 45, the bearing block. 23 and barrel end 24 :maybe lifted away fromthe frame supported by the jib 42 ina position .clear ofthe open; end of the barrel, but ready to-be easily quickly reassembled -therewiths With the parts position, the barrel 12 may, have 1 placed therein objects to betumbled (not shown) together with; conventional polishing or, burnishingmaterial-such 'assteel shot and. soap-andwater, as is well-known .in the art. To protect .theend mu 14.01? tbebar el o sc r ation.

I desirably insert a metal plate 48 adjacent the barrel, the frame 4 maybe swung into vertical position and the end wall 14 of the cylinder which may be replaced when worn. The barrel, in accordance with common practice, is also desirably lined with wood inserts 49 which may be swollen into place and which in turn retain the plate 48 in position. y Y

When the barrel hasbeen charged as indicated and the bearing block 23 and barrel end 24 again clamped in position as described, the frame 4 .rnay be swung to horizontal position in its vertibarrel. end '24-have been removed the barrel may be emptied of its contents.

To maintain the frame 41in its selective positions, I provide latching means such as the spring pressed finger 50 (Figure 5') suitably carried by one of the side members 5 and :engageable in notches 51 arouately arranged upon one of tlie trunnion sockets 7 The finger so may be heldout of engagement with the notches 51 by means of a handle 52 thereon whichmay beqturned to be received in a a laterally directed slot 53 when the finger is in retracted position.

Obviously, the invention is not limited to the details of construction shown herein for purposes of, illustration. Furthermore, it is not indispensable that allfeatures of the invention be employed conjointly since various combinations and sub-combinations may be advantageously used. 1, T
